Use thedtrequest parameter to obtain estimated UV Index value for any point in time (hours, days, months, years).
Please note, if there is no ozone level
provided estimated UV Index will be based on a current Ozone level from OMI dataset.
For 30 minutes intervals UV Index Forecast for any date use the UV Index Forecast method.

In common UV levels increase by 4% for every 300 metres. Though the elevation could be explicitly identified by (lat, lng) using Google Maps API on OpenUV server side we chose to delegate that task to our clients due
performance and Google Maps API limitation reasons (2,500 req/daily from one IP Address). Please reference the official Google Documenantion for how to obtain elevation from Google Maps API.

As service will grow we plan to implement elevation datasets available as a part of OpenUV API.

On average, the Ozone Monitoring Instrument (OMI) products available on EOSDIS NASA FTP portal within 3.5 hours after the observation time.Ozone data for a specific location is cached on our servers for 1 hour.

There is a bunch of cool things you could do with raw UV Index value in your app, for instance show time to burn based on user's skin type obtained from Apple Health Kit or keep track of UV Index exposure
and calculate Vitamin D intake. Check the Knowledge Base and Code Samples pages for more ideas how to use UV Index in your apps.
